ROIAzimuthal can now be restricted to an azimuthal-angle sector in addition to its Q/d range, enabling STXM-style directional ROIs. phi bounds are optional (both-or-neither); absent means a full 360 ring, so existing Q-only azimuthal ROIs are unchanged. - ROIElement::CheckROI gains a phi_deg argument; box/circle ignore it. - MarkROI gains an optional phi_map; ROIMap builds it from Phi_rad alongside the resolution map only when azimuthal ROIs are present. - phi bounds are normalized to [0,360) and wrap-around sectors are supported (phi_min > phi_max). - ROIConfigAzim carries phi_min/phi_max (kept trivially copyable for the union; phi_min == phi_max means full ring). No phi crosses the wire yet (CBOR/API wiring follows separately). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
